Question

Human blood gives rise to an osmotic pressure of approximately 7.65 atm at body temeprature, 37°c. Hence, molarity of an intravenous glucose solution which have the same osmotic pressure as blood is:

Answer 1

here is your answer ⤵️

Use the formula

$\pi = CRT \:$

Now put the given values.

$\frac{7.65}{0.0821 \times 31} \: = C$

from here we get

C=M =0.3 M.

Answer 2

Answer:

0.3M.

Explanation:

Osmotic pressure may be defined as the pressure required to stop the flow of osmosis.

The osmotic pressure can be calculated by the formula

π = CRT

C = π / RT

Here, C is molarity , π is osmotic pressure = 7.65, R is Rydberg constant = 0.0821 and T is temperature = 37°C.

C = 7.65 / 0.0821 × 37

C = 0.3 M

Thus, the molarity of intravenous solution is 0.3M
